1. Starting uEFI BIOS Setup

The AM5030 is provided with a Kontron-customized, pre-installed and configured version of
Aptio® (referred to as uEFI BIOS in this manual), AMI’s next generation BIOS firmware based
on the Unified Extensible Firmware Interface (uEFI) specification and the Intel® Platform Inno­vation Framework for EFI. This uEFI BIOS provides a variety of new and enhanced functions
specifically tailored to the hardware features of the AM5030. This user guide reflects the uEFI
BIOS version R12.

To take advantage of these functions, the uEFI BIOS comes with a Setup program which pro­vides quick and easy access to the individual function settings for control or modification of the
uEFI BIOS configuration.

The Setup program allows the accessing of various menus which provide functions or access
to sub-menus with more specific functions of their own. The individual menus and the config­urable functions are described in this guide.

To start the uEFI BIOS Setup program, follow the steps below:

1. Power on the board.

2. Wait until the first characters appear on the screen (POST messages or splash screen).

3. Press the <F2> key.

4. If the uEFI BIOS is password-protected, a window such as the one below will appear:

Enter either the User password or the Administrator p assword (refer to Chap ter 6, Secu­rity Setup, for further information), press <RETURN>, and proceed with step 2.

5. A Setup menu with the following token attributes will appear.
The currently active menu and the currently active uEFI BIOS Setup item a re highlighted
in white.

1.1 Main Setup Menu

The Main setup menu is the first screen that appears after starting the Setup program.
At the top of this screen and all of the other major screens, there is a setup menu selection bar ,

which permits access to all of the other major setup menus. These menu s are selected via t he
left-right arrow keys.

All setup menu screens have two main frames. The left frame displays all the functions that can
be configured. They are displayed in blue. Functions displayed in gray provide information
about the status or the operational configuration.

The right frame displays the key legend. Above the key legend there is an area reserved for a
text message. When a function is selected in the left frame, it is displayed in white. Often a text
message will accompany it.

Group (PCI-SIG). ATS consists of a set of PCI transactions that allow the optimization of VT-d
address translations These extensions enable I/O devices to request translations from the root
complex and for the root complex to return responses for each translation request.

Note: This function is available only when the function Intel(R) VT-d is set to Enabled.

8. The uEFI Shell

The Kontron uEFI BIOS features a built-in and enhanced version of the uEFI Shell. For a de­tailed description of the available standard shell scripting refer to the EFI Shell User’s Guide.
For a detailed description of the available standard shell commands, refer to the Shell Com­mand Manual 1.0. Both documents can be downloaded from the EFI and Framework Open
Source Community homepage (https://efi-shell.tianocore.org) under the “Documents and
Files” section.

Please note that not all shell commands described in the Shell Command Manual 1.0 are pro­vided by the Kontron uEFI BIOS.

8.1 Introduction, Basic Operation

The uEFI Shell forms an entry into the uEFI boot order and is the first boot option by default. It
is simply started by putting the uEFI Shell first in boot and running the board as usual.

8.1.1 Shell Startup

If the shell is executed, it displays its signon message followed by a list of detected devices.
The output produced by the device mapping table can vary depending on the board’ s con figu­ration.

The kboot comma nd boots a legacy OS. Boot device can be selected in
a very flexible way. If the requested device is not present, boot returns
to shell. The kboot command cannot boot native uEFI operating
systems. But since these are bootable from shell by calling their
bootloader, this is not necessary either. If a req ueste d device is prese nt
but not bootable, uEFI continues to boot with the next bootable de vice in
the boot order.

DESCRIPTION: Creates a RAMdisk of variable size. Can be very useful to perform file

operations when no real filesystem is connected to the system.
Note: The RAMdisk loses its mount point name after all drives are

remapped by the map -r command. The RAMdisk will then be
enumerated as any other connected drive and gain a mount point
name like “fs0”. This is not a bug of the kmkramdisk command
but a normal function of the uEFI framework.

Note: Because there is no application which triggers the W atchdog, the

system will be reset after 16 seconds in this case. This command
should be invoked from a script, followed by an operating system
boot, and the OS then has to start triggering the Watchdog.

8.3 uEFI Shell Scripting

8.3.1 Startup Scripting

If the ESC key is not pressed and the timeout is run out, either the Kontron Flash-stored st artup
is executed, if present, or the uEFI specified startup.nsh script located under \efi\boot\
on any of the attached drives is executed. If none of the st artup scripts is present, or the startup
script terminates, the default boot order is continued.

If the shell is started with no interaction, it tries to execute some startup scripts automatically.
It searches for scripts in the following order:

1. Kontron Flash-stored startup script

2. If there is no Kontron Flash-stored startup script present, the uEFI specified startup.nsh
script is used. This script must be located on any of the attached F AT formatted disk drives un­der \efi\boot\startup.nsh.

If both startup scripts are absent, the shell terminates and the default boot order is continued.

8.3.2 Create a Startup Script

Startup scripts can be created using the uEFI She ll built-in editor edit or under any OS with a
plain text editor of your choice. To create a startup.nsh type shell script, simply save the
script on any FAT-formatted drive attached to the system under \efi\boot\startup.nsh.
To create a Kontron Flash-stored startup script, the script is to be saved anywhere on a FAT­formatted drive attached to the system and stored to Flash using the built-in uEFI Shell com­mand kbootnsh.

8.3.3 Examples of Startup Scripts

8.3.3.1 Automatic Booting from USB Memory Stick

Automatic booting is made from a USB memory stick, if present, otherwise the boot is made
from the harddrive.

kboot -t usb-harddrive

kboot -t harddrive

P R E L I M I N A R Y

If neither a USB memory stick nor a harddrive is present, the boot order is continued.

8.3.3.2 Switch On Clock Spreading Prior to Booting from Harddrive

kclsp -e

kboot -t harddrive

If no harddrive is present, the default order is continued.

8.3.3.3 Execute Shell Script on Other Harddrive

This example executes the shell script named bootme.nsh located in the root of the first de­tected disc drive (fs0).

AM5030 uEFI BIOS Updating the uEFI BIOS

9. Updating the uEFI BIOS

BIOS updates are typically delivered as an update CD ISO image. This ISO image needs just
to be burned to a CD and booted. Follow the menu for updating the uEFI BIOS. For further in­formation refer to the update CD documentation.

9.1 BIOS Redundancy Strategy

The AM5030 has two sets of EFI Flash chips to form an EFI redundancy strategy. Basic idea
behind that is to always have at least one working EFI available regardless if there have been
any flashing errors or not.

9.2 Updating Strategy

To always maintain at least one EFI Flash correct, the update CD uses the following update
procedure:

1. Switch to the second Flash.
Since the update CD always changes the Flash chip prior to doing any updates, the uEFI
BIOS that was used to actually boot the board and is therefore known to be good is pre­served for backup.

2. Update the second Flash.
This flash is now selected as active boot Flash.

The update CD will not allow to flash both chips at a time. Flashing both chips would destroy
the backup version and therefore break the redundancy.

If you want to have the same BIOS version on both Flash chips, then simply run the update CD
twice.

9.3 Fallback Mechanism

In case of one EFI being corrupted and therefore the board not starting up, the IPMI controller
automatically switches to the other Flash and resets the board. The board should now come
up successfully from the other not corrupted image. The flashing procedure can now be restart­ed to restore the broken image.

9.4 Flash Selection by IPMI Command

Usually the active Flash is selected by the IPMI controller. The Flash bank can be switched via
an IPMI OEM command. This command is used by the update CD. See the IPMI manual for
further information.

P R E L I M I N A R Y

Updating the uEFI BIOS AM5030 uEFI BIOS

9.5 Flash Selection by DIP Switch

On some cases it may be necessary to force the board to boot from the other Flash without
using the appropriate IPMI command to switch the Flash chips. In this case, the onboard DIP
switch SW3, switch 2, is used to toggle the active Flash. Note that this switch does not “select”
one Flash chip. It toggles the currently active Flash. Therefore, the IPMI controller will still
switch the flashes by command or in case of the active Flash is defective. Note that using this
DIP switch does not change the way the update CD handles the update procedure. Refer to
the AM5030 user guide for further information.

9.6 Determining the Active Flash

Sometimes it may be necessary to check which Flash is active. On the AMI Aptio-based uEFI
BIOS, the information is available using the EFI shell command “kboardinfo”. For further infor­mation, refer to the “kboardinfo” section in the uEFI Shell chapter of this document.
